    Summary

    Rhizoctonia bataticola isolates show significant variation in growth, sclerotia, and virulence across different hosts. Some strains, particularly from brinjal and beans, exhibit higher virulence and fungicide resistance, indicating distinct pathogen strains.

    Area of Science:

    • Plant Pathology
    • Mycology
    • Agricultural Science

    Background:

    • Rhizoctonia bataticola is a significant plant pathogen causing considerable crop losses.
    • Understanding pathogen variability is crucial for effective disease management strategies.

    Purpose of the Study:

    • To investigate the variability among eight Rhizoctonia bataticola isolates from diverse hosts.
    • To characterize differences in growth rate, media effects, sclerotial characteristics, temperature tolerance, fungicide sensitivity, and virulence.

    Main Methods:

    • Comparative analysis of eight Rhizoctonia bataticola isolates.
    • Evaluation of growth rate, sclerotial development, and virulence on various hosts.
    • Assessment of isolate response to different media, incubation temperatures, and fungicides.

    Main Results:

    • Significant variations observed among isolates in all studied characters.
    • Isolates from brinjal and beans demonstrated high virulence and reduced sensitivity to fungicides.
    • Distinct differences in growth patterns and sclerotial formation were noted.

    Conclusions:

    • The study confirms the existence of distinct strains within Rhizoctonia bataticola.
    • Pathogen variability has implications for fungicide efficacy and disease control.
    • Host-specific adaptations may contribute to the observed strain differences.
